The first full-colour image of Comet 67P is a composite of different images using the full spectral range of Rosetta's camera
AGUThe first non-greyscale image of Comet 67P
has revealed it to be a bright, reddish-brown world. A
composite image of the distant, icy world has been created using
the full colour range of Rosetta's Osiris camera, with another
high-resolution snap coming soon.
As Rosetta doesn't have a
conventional colour camera researchers had to use a range of images
from different parts of the spectrum and combine them for a
full-colour shot. The resulting image is blurred as the comet moved
in the time it took to take all the pictures required.
The
composite image reveals a dark red and brown body, similar in
colour to many rocks seen on Mars. Blurring on the image was
partially removed up by a poster on Reddit who cleared up the
composite picture.

The image was taken using the full spectral range of the
Narrow Angle Camera on the Osiris imaging system. More details
about the colour of Comet 67P will be revealed at the annual
meeting of the American Geophysical Union in San Francisco on 18
December. A higher resolution colour image will also be shown at
the conference.
